英文小作文：

Extinction is a sad reality that we must face, whether it"s a species, a language, or even an ecosystem that is disappearing from our planet. We must cherish what we have left and work towards preserving our biodiversity for future generations. At the same time, we must also recognize that extinction is a natural process that occurs over millions of years, but it"s still a sobering reminder of our impact on the environment and our responsibility to protect it.

As we witness the passing of these once-living things, we must remember that extinction is not the end of life itself, but rather a transition to new forms and ways of being on this planet. We must strive to ensure that future generations will have a world full of diversity and life, and that they will inherit a planet that is still rich in biodiversity and sustainability.
